Three Woodinville rules to settle before design

  1. The Woodinville rule

    Sammamish River and Little Bear Creek

    Woodinville's shoreline program reaches 200 feet landward from the ordinary high water mark of the Sammamish River and Little Bear Creek, and 200 feet from their floodways, under WMC 21.70. Critical areas inside that band follow a separate chapter, WMC 21.77.

    What we do

    We confirm on the shoreline map whether your address falls in that band before any plan is sketched.

  2. The Woodinville rule

    Hillside lots and landslide buffers

    A slope of 40 percent or steeper with at least 10 feet of vertical relief counts as a steep slope under WMC 21.51.110. The minimum buffer from a landslide hazard equals the height of the slope or 50 feet, whichever is greater, and a qualified professional can justify reducing it to no less than 10 feet.

    What we do

    We pull the city's geologic hazard layers for your parcel before an addition or deck is drawn.

  3. The Woodinville rule

    Two to five weeks of plan review

    The city's permitting FAQ lists 2 to 5 weeks of review for a single-family addition or alteration permit. Plumbing and mechanical permits for a house are listed at 1 week.

    What we do

    We set your start date from those listed turnaround times.

All three are checked against your address while the design is still on paper.

We were nervous about hiring a contractor because we were first-time homeowners, but Volcano Builders made it easy to understand. They made everything clear and helped us stick to our budget. I'm very happy with how everything turned out.

Overall, we had a great time with Volcano Builders. There were a few small delays, but they were clear in their communication and kept things moving. The last kitchen remodel turned out great, and the quality seems like it will last for a long time.

I recently hired Bar from Volcano Builders to remodel my bathroom. Overall, the experience was satisfactory. Bar was professional and communicated well throughout the project. The work was completed on time and within budget. The quality of the remodel met my expectations, though there were a few minor details that could have been improved. I would recommend Bar for anyone looking for a reliable contractor for bathroom renovations.

Bar Unger, founder of Volcano Builders

I'm Bar, founder of Volcano Builders. I have been building for 20+ years, and our main office is in Bellevue, a short drive from Woodinville. Most remodeling problems start before any work does: a vague price, a missed permit step, nobody answering the phone. So every project we take on gets a written, itemized price before work starts, a design and permit plan built around your city's rules, and one project manager you can actually reach.

Guide

Remodeling a Woodinville home: permits, river rules, hillsides and ADUs

How a Woodinville permit moves

Woodinville Development Services takes most applications through its online Permit Portal. Plans and documents are uploaded as PDFs, part of the fee is paid at submittal, and revisions and inspection requests go through the same account.

Residential construction uses the city's Combined Building Permit. Before it is issued, the city asks for the contractor's Washington State contractor license and a Woodinville business license, and the permit and approved plans then arrive as PDFs in the portal.

The city's permitting FAQ lists 2 to 5 weeks for a single-family addition or alteration, 4 to 7 weeks for a new single-family house, and 1 week for residential plumbing or mechanical work. Tree removal tied to a building permit is reviewed under that permit rather than on a separate one.

Rivers, wetlands and hillsides

Two waterways define Woodinville's shoreline: the Sammamish River, which flows north and west through the city, and Little Bear Creek, its tributary through the west side of downtown. Land within 200 feet of either, their floodways and associated wetlands sit under the shoreline master program in WMC 21.70 through 21.77.

Away from the shoreline, WMC 21.51 regulates wetlands, aquifer recharge areas, frequently flooded areas, fish and wildlife habitat and geologically hazardous areas, the last covering erosion, landslide and seismic hazards. The city treats its critical area maps as a reference only, and a site investigation decides what is actually present on a lot.

ADUs and backyard cottages

Where the zone allows them, WMC 21.41.020 permits up to two accessory dwelling units per parent lot. Each needs at least 300 and no more than 1,500 square feet of habitable floor area, and it can sit inside the house, attach to it or stand alone.

An existing detached garage or other legally built enclosed structure can be converted even if it does not meet current coverage or setback standards, a detached ADU may sit at zero setback from a public alley, and ADUs cannot be rented for fewer than 30 nights at a time.

Woodinville housing and what it needs

Woodinville's homes are young for the region. The Census Bureau's 2020 to 2024 American Community Survey puts the median year built at 1995, and the 1980s were the busiest decade, with about a quarter of today's homes. Roughly one in five predates 1980.

Just over half of the city's housing units are detached houses. A 1980s house often keeps its original bathroom and kitchen layouts, so many projects here are room remodels rather than full rebuilds, and each one is priced in writing before work begins.

Permits and turnaround times: City of Woodinville Development Services web pages and permitting FAQ, checked September 2026. Shoreline and critical areas: Woodinville Municipal Code chapters 21.51, 21.70 and 21.77. ADUs: WMC 21.41.020 (Ordinance No. 792, 2025). Housing: US Census Bureau, American Community Survey 2020 to 2024 5-year estimates.

Questions

Woodinville remodeling questions

How long does a Woodinville bathroom remodel permit take?

If the remodel needs a building permit, the city lists 2 to 5 weeks of review for a single-family alteration, while a plumbing permit alone is listed at 1 week. We file the application through the city's Permit Portal and build those times into your schedule.

What does a Woodinville remodeling contractor handle on the permit?

On our jobs, all of it. We prepare the drawings, upload them to the Permit Portal, answer the plan reviewer's comments and book inspections. The city also requires the contractor's state license and a Woodinville business license before it issues the permit.

Does living near the Sammamish River or Little Bear Creek change my project?

It can. Land within 200 feet of either waterway, or of their floodways, falls under the shoreline master program, and critical areas there follow WMC 21.77. We check the shoreline map for your address before any design starts.

Can I build a backyard ADU in Woodinville?

In most residential zones, yes. WMC 21.41.020 allows up to two ADUs per parent lot, each between 300 and 1,500 square feet of habitable floor area, and a legally built detached garage can be converted. Short stays under 30 nights are not allowed.

Is a deck on a sloped Woodinville yard harder to permit?

Sometimes. A slope of 40 percent or more with 10 feet of rise is a steep slope under WMC 21.51.110, and a landslide hazard keeps a minimum buffer equal to the slope height or 50 feet, whichever is greater. Work on those slopes also needs a mitigation plan for drainage, erosion control and replanting.

What does a kitchen remodel in Woodinville cost?

The price follows the scope: keeping plumbing and walls where they are costs less than moving them, and an older house can need electrical or plumbing updates once it is opened. You get an itemized written price before anything starts, and typical ranges are in our Remodeling Pricing Guide.
